Do you need to eyeball through fastq alignment file, with special features to highlight the quality score of each bases?
Introducing fastqviz, a Streamlit app which can do just that. I made it quite some time ago to visualize some amplicon data for my own project.
You can upload your fastq file. The fastqviz viewer will show the alignment, along with color highlighting quality of each bases (pink is high quality, dark is low). Scroll sideways to explore through sequence length.
Please let me know if you have any feature requests!
